SPIRAL SLIDEWAY.

Patented .April 17, 1906.

To aZZ whom it may concern:

Be it known that I, WILLIAM HUME Lo- GAN, a citizen of the UnitedStates, residing at Louisville, in the county of J efferson and State ofKentucky, have invented certain new and useful Im rovements in SpiralSlideways; and I do dec are the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, vand to the gures of reference markedthereon, which form a part of this specification.

My invention relates to amusement devices and package-chutes, and hasfor its object to provide'a spirally-arranged slideway for pleasureseekers or packages to slide down.

A further object of my invention is to pro.- vide a device for thesepurposes which is particularly simple in its construction, veasy to setup and knock down, safe, strong, and efficient.

With these objects in view my invention consists particularly in thenovel spirally-arrarled outside safety-guard.

y invention further consists in the novel central supporting means. p

My invention further consists in certain other details of constructionand in combination of parts, which will beirst fully described and`afterward specifically pointed out in the appended claims. i

Referring to the accompanyin drawings, Figure 1 is a perspective view oft e slideway constructed in accordance with my invention.' Fig. 2 is al;horizontal cross-section taken on ine 2 2 of Fig. '1. Fig. 3 is afragmentary detail view of a part of slideway, 4vertical wall,safety-screen, and outer spiral screen. Fig. 4 is a fragmentary viewshowing a section of central. stand-pipe and illustrating the slidewaydirectly supported b the outer vertical supports, the vertical wall andsafety-screen not being shown. l Fig. 5 is a top plan of theconstruction shown in Fi 4. l

ike numerals of reference indicate the same parts throughout the severalfigures, in -which-- 1 indicates the spiral slideway, made of sectionsor nights 1 and suitably secured to a stand-pipe 2, composed of sections2', each of said sections having a core 3, Fig. 4, which enters thesection immediately above. By this construction the device may becoinpactly shipped and the parts rapidly assembled.

4 indicates the vertical wall, which follows the spiral slideway, towhich it is secured, said wall being for the purpose of providing astiffening for the slideway, greatly strengthening the same and actingto hold the roper curve or contour in the slideway, w `ch is shown, Fig.3, having its outer edge higher than its inner edge, .said wallpreferablynot extending above the edge ofthe slideway.

In Fig. 1 I illustrate a-series of outside vertical supports 5,preferably T-shaped in crosssection, and supportin the slideway 1 bymeans of the braces or 'brackets 6. Resting on said braces or bracketsis a safety-screen 7, which follows the spiral slideway and fills thespace between the same and vertical supports 5, which are at a distanceand out of reach from the slideway, so that the passeners could not beinjured by holding out their hands or arms during their descent, thesafety-screen guarding against any one falling over the vertical wal 4.It will be noticed that this safety-screen is made, preferably, of aseries of heavy wires or light iron rods 7 which are 'laid spirally uponthe braces or brackets 6. This construction is preferable to that of asmall-mesh wire, for

the reason that the interstices therein and.

the weave of the wire present a somewhat roughened surface, and would beinjurious to the hands, arms, or garments of the passengers, while in mypresent construction the safety-screen would ofer little or no frictionto any object in contact therewith. The

outside spiral guard-wall 8 is constructed simi-v larly to thesafety-screen, as shown, and this construction is much more preferablethan a cylindrical cage or covering inclosing the entire tower,principally on account of the much lower cost of my present constructionand on account of the improved appearance,

and also because it allows a better view of the slideway and itspassengers. A suitable passage '9 ,leads to the top of the slideway, anda suitable guard 10 is located at the bottom of slideway to shield anyderangement of dress which might occur. I

n Fig. 4 I illustrate a section 2 of the central stand-pipe 2, showingalso section of slideway 1 secured thereto.

Having thus described the several parts of my invention, its operationis obvious. The passengers are conveyed by any -suitable ,means to thepassage lat the top of the slideway, where their descent is started, andthey slide down spirally, making their exit at the bottom of theslideway. This device is particularly adapted also to be used as apackage-chute to be used in stores for conveying packages and bundlesfrom one Hoor to another.

What I claim as my invention, and desire to secure by Letters Patent ofthe United States, is-

1. A. spiral slideway having a central supporting means a safety-screencomprising a series of spirally-arranged wires, said safetyscreenbeingon the outside of said slideway,

and an cuter s iral guard-wall comprising a series of spira ly-arrangedwires, substantially as described.

2. A spiral slideway having a central supporting means, a verticalstiffening-wall secured to said slideway, an outer guard-wallconstructed of a series ci spirally-arranged wires, and a safety-screeninterposed between the said slideway and the saidl outer guard- Wall,said safety-screen being constructed of a series of spirally-arrangedwires, substantially as described. y

3. A spiral slideway having adish or curve therein and having a centralsupporting means constructed in sections, a spirally-arranged verticalstiHening-wall secured to the outer edge of said slideway, the top edgeof said Wall extending only to the top edge of said slideway, wherebythe dish or curve of the slideway is. preserved regular and unbroken,substantially as described.

4. A spiral slideway having its central supporting means constructedsections, a core 1n each of. said sections arranged to enter itsadjacent section, and a series of flights constructed independent of thecentral sectional 1 supporting means and secured to thel said sectlonalcentral supporting means, substantially as described. v
